McSween History, Family Crest & Coats of Arms

Irish names tend to vary widely in their spelling and overall form. The original Gaelic form of the name McSween is Mac Suibhne, which is derived from the word "suibhne," which means "pleasant."

Early Origins of the McSween family

The surname McSween was first found in County Donegal (Irish: Dún na nGall), northwest Ireland in the province of Ulster, sometimes referred to as County Tyrconnel. The name is derived from Suibhne O'Neill, who was a chieftain in Argyll, Scotland. His descendants migrated to Ireland as gallowglasses (mercenaries) prior to 1267. The three great septs of this name finally established themselves in Tirconnell in 14th century; they were known as MacSweeney Fanad, MacSweeney Banagh, and MacSweeney na dTuath, who were commonly referred to as 'MacSweeney of the Battleaxes.' They later became attached to the MacCarthys in the south and acquired their own territories and castles in Muskerry in County Cork.

United States McSween migration to the United States +

During the 19th century thousands of impoverished Irish families made the long journey to British North America and the United States. These people were leaving a land that had become beset with poverty, lack of opportunity, and hunger. In North America, they hoped to find land, work, and political and religious freedoms. Although the majority of the immigrants that survived the long sea passage did make these discoveries, it was not without much perseverance and hard work: by the mid-19th century land suitable for agriculture was short supply, especially in British North America, in the east; the work available was generally low paying and physically taxing construction or factory work; and the English stereotypes concerning the Irish, although less frequent and vehement, were, nevertheless, present in the land of freedom, liberty, and equality for all men. The largest influx of Irish settlers occurred with Great Potato Famine during the late 1840s. Research into passenger and immigration lists has brought forth evidence of the early members of the McSween family in North America:
